What is the purpose of using disposable electrodes in ECG testing?

To reduce the need for signal amplification

To ensure a single-use and minimize contamination

Using disposable electrodes in ECG testing serves the purpose of ensuring a single-use and minimizing contamination. Disposable electrodes are designed for one-time use, which helps to prevent cross-contamination and the spread of infections between patients. By using new electrodes for each patient, healthcare settings can maintain a higher standard of hygiene and safety, which is paramount in medical environments. This practice not only protects the patients but also reduces the risk to healthcare providers.

In addition, the non-reusable nature of these electrodes aligns with infection control protocols, emphasizing the importance of patient safety and public health. Thus, the primary advantage of disposable electrodes lies in their role in promoting cleanliness and preventing the transmission of pathogens during ECG testing.
